Replacing the filter unit
1
When your non-washable filter unit needs replacing the appliance will
display the pattern shown. To replace the non-washable filter unit,
follow these steps. Ensure the appliance is unplugged, if the appliance
has been in use, leave for 1 to 2 hours before replacing the filter unit
to allow the appliance to cool down completely. Your Dyson appliance
is programmed to remind you to replace the filter unit after 12 months
based on 12 hours usage a day. Please note your indicator will
activate sooner with more use. The indicator is only a guide and you
may need to replace the filter unit more regularly.
